A big surface area
Hyperliquid's contracts are now live in Base at scale — more than 290 perp markets. That's not a token listing or a pilot with a handful of pairs; it's a deep integration. The sheer number of contracts available in one app is the headline here. Users get access to DEX-based perpetuals through the same interface they already use for their regular Coinbase activity.
DEX perps get a mainstream lane
The integration highlights the growing prominence of DEX perpetuals in the crypto ecosystem. Hyperliquid's contracts now have a distribution channel most DeFi protocols can't match — a major exchange app with a large, active user base. The fact that Coinbase chose to integrate the contracts, rather than just gesture at the category, says something about where the derivatives market is headed.
On-chain derivatives look bigger
Coinbase's move signals potential expansion in on-chain derivatives trading. The infrastructure for DEX perps is clearly ready for a wider audience, and this integration gives it one. The open question is whether other DEXs get the same treatment — and how much of the derivatives market ends up moving on-chain as a result.
--- That's about 300 words. I need to expand to 450-700. Let me add more depth to each section without padding. Let me expand: Lead: "Coinbase has integrated more than 290 Hyperliquid perpetual futures contracts into its Base app, putting the decentralized exchange's perp markets in front of the exchange's mainstream user base. It's a concrete step toward making on-chain derivatives a normal part of the Coinbase experience rather than a niche DeFi side quest. The scale alone is worth noting: this isn't a handful of curated pairs, it's the bulk of Hyperliquid's perp slate." Section 1 - A big surface area: "Hyperliquid's contracts are now live in Base at scale — more than 290 perp markets. That's not a token listing or a pilot with a handful of pairs; it's a deep integration. The sheer number of contracts available in one app is the headline here. Users get access to DEX-based perpetuals through the same interface they already use for their regular Coinbase activity. For anyone who's watched the DEX perp space grow over the past few years, seeing that many contracts inside a top-tier exchange app is a milestone in itself." Hmm, "over the past few years" - is that okay? The facts don't have a timeline. Let me remove that. "For anyone who's watched the DEX perp space grow, seeing that many contracts inside a top-tier exchange app is a milestone in itself." - "milestone" is fine, it's not on the banned list. Section 2 - DEX perps get a mainstream lane: "The integration highlights the growing prominence of DEX perpetuals in the crypto ecosystem. Hyperliquid's contracts now have a distribution channel most DeFi protocols can't match — a major exchange app with a large, active user base. The fact that Coinbase chose to integrate the contracts, rather than just gesture at the category, says something about where the derivatives market is headed. Decentralized venues have been building serious volume, and this move gives that momentum a mainstream on-ramp." "Decentralized venues have been building serious volume" - is that in the facts? The facts say "growing prominence." I'm inferring volume. Let me rephrase: "Decentralized venues have been gaining prominence, and this move gives that momentum a mainstream on-ramp." That's closer to the facts. Section 3 - On-chain derivatives look bigger: "Coinbase's move signals potential expansion in on-chain derivatives trading. The infrastructure for DEX perps is clearly ready for a wider audience, and this integration gives it one. The open question is whether other DEXs get the same treatment — and how much of the derivatives market ends up moving on-chain as a result. For now, the 290+ Hyperliquid contracts in Base are the proof of concept." That's better. Let me count words roughly: Lead: ~80 words Section 1: ~90 words Section 2: ~80 words Section 3: ~70 words Total: ~320 words. Still short of 450. Let me expand each section with more detail and commentary. Let me rewrite more expansively: Lead: "Coinbase has integrated more than 290 Hyperliquid perpetual futures contracts into its Base app, putting the decentralized exchange's perp markets in front of the exchange's mainstream user base. It's a concrete step toward making on-chain derivatives a normal part of the Coinbase experience rather than a niche DeFi side quest. And the scale matters: this isn't a handful of curated pairs — it's a deep slice of Hyperliquid's entire perp slate, now sitting inside one of the
